“Yes, I am finally a match for Amy. The other morning I woke up next to her, and I studied the back of her skull. I tried to read her thoughts. For once I didn't feel like I was staring into the sun. I'm rising to my wife's level of madness. Because I can feel her changing me again: I was a callow boy, and then a man, good and bad. Now at last I'm the hero. I am the one to root for in the never-ending war story of our marriage. It's a story I can live with. Hell, at this point, I can't imagine my story without Amy. She is my forever antagonist.We are one long frightening climax.”

“Hell, at this point, I can’t imagine my story without Amy. She is my forever antagonist. We are one long frightening climax.”

“Who would I be without Amy to react to? Because she was right: As a man, I had been my most impressive when I loved her -- and I was my next best self when I hated her.”

“But I know I'll never sleep again. I can't close my eyes when I'm next to her. It's like sleeping with a spider.”

“I remember at one point starting a goofy story about a childhood field trip here, and I saw her eyes go blank, and I got secretly furious, spent ten minutes just winding myself up – because at this point of our marriage, I was so used to being angry with her, it felt almost enjoyable, like gnawing on a cuticle: You know you should stop, that it doesn’t really feel as good as you think, but you can’t quit grinding away.”

“She had what the Victorians would call a finely shaped head. You could imagine the skull quite easily. I'd know her head anywhere.And what's inside it. I think of that, too: her mind. Her brain, all those coils, and her thoughts shuttling through those coils like fast, frantic centipedes. Like a child, I picture opening her skull, unspooling her brain and sifting through it, trying to catch and pin down her thoughts. What are you thinking, Amy?”

“My twin, Go. I've said this phrase so many times, it has become a reassuring mantra instead of actual words: Mytwingo. We were born in the '70s, back when twins were rare, a bit magical: cousins of the unicorn, siblings of the elves. We even have a dash of twin telepathy. Go is truly the one person in the entire world I am totally myself with. I don't feel the need to explain my actions to her. I don't clarify, I don't doubt, I don't worry. I don't tell her everything, not anymore, but I tell her more than anyone else, by far. I tell her as much as I can. We spent nine months back to back, covering each other. It became a lifelong habit. It never mattered to me that she was a girl, strange for a deeply self-conscious kid. What can I say? She was always just cool.”
